e2label - Change the label on an ext2/ext3/ext4 filesystem SYNOPSIS
e2label device [ new-label ] DESCRIPTION
e2label will display or change the filesystem label on the ext2, ext3, or ext4 filesystem located on device. If the optional argument new-label is not present, e2label will simply display the current filesystem label. If the optional argument new-label is present, then e2label will set the filesystem label to be new-label. Ext2 filesystem labels can be at most 16 characters long; if new-label is longer than 16 characters, e2label will truncate it and print a warning message. It is also possible to set the filesystem label using the -L option of tune2fs(8). AUTHOR

e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem SYNOPSIS
e2undo [ -f ] [ -h ] [ -n ] [ -o offset ] [ -v ] [ -z undo_file ] undo_log device DESCRIPTION
e2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesystem found on device. This can be used to undo a failed operation by an e2fsprogs program. OPTIONS
-f Normally, e2undo will check the filesystem superblock to make sure the undo log matches with the filesystem on the device. If they do not match, e2undo will refuse to apply the undo log as a safety mechanism. The -f option disables this safety mechanism. -h Display a usage message. -n Dry-run; do not actually write blocks back to the filesystem. -o offset Specify the filesystem's offset (in bytes) from the beginning of the device or file. -v Report which block we're currently replaying. -z undo_file Before overwriting a file system block, write the old contents of the block to an undo file. This undo file can be used with e2undo(8) to restore the old contents of the file system should something go wrong. If the empty string is passed as the undo_file argument, the undo file will be written to a file named e2undo-device.e2undo in the directory specified via the E2FSPROGS_UNDO_DIR environment variable. WARNING: The undo file cannot be used to recover from a power or system crash. AUTHOR
